    The paper analyzes the main causes of degradation of Mesopotamian Marshlаnds. It is shown that the recovery of the marshland is possible through the combined efforts of several countries involved in the implementation of the UNEP International Plan of the territories rehabilitation, which was taken in 2003.Дан анализ основных причин деградации маршлендов Месопотамии. Показано, что восстановление болот возможно с помощью объединенных усилий нескольких стран, принимающих участие в выполнении Международного плана реабилитации территорий, принятого ЮНЭП в 2003 г

    The paper presents the results of the calculation of air pollution from closed-cycle gas turbine plant (CCGT plant) “Tereshkovo” for basic conditions: peak; regular winter, summer, emergency taking into account the high-rise buildings. Dispersion calculations showed that the concentrations of pollutants at the border of SPZ and residential buildings will not exceed sanitary standards of air quality. On the basis of calculation found that surface concentrations of pollutants do not exceed the standards (MАC) of air cleanliness in the area of residential development; this determines the admissibility of the object in the vicinity of natural complexes and have shown the possibility of reduce the size of SPZ to the border with the construction of a school (up to 200 m in the south- east direction) and to the border of the residential development (up to 280 m in the southern direction).В статье представлены результаты расчета загрязнений атмосферы от парогазотурбинной теплоэлектростации (ПГТЭС) «Терешково» для основных режимов: пиковый (при Т нв = -28 °С); штатный зимний; летний; аварийный, с учетом многоэтажной застройки. Расчеты рассеивания показали, что концентрации загрязняющих веществ на границе нормативной СЗЗ, на границе с селитебной застройкой не превысят санитарно-гигиенических нормативов качества атмосферного воздуха. На основе расчета установлено: приземные концентрации загрязняющих веществ не превышают нормативов чистоты (ПДК) атмосферного воздуха в зоне жилой застройки; это определяет допустимость размещения объекта в непосредственной близости от природных комплексов и дает возможность сократить размер СЗЗ до границы со строящейся общеобразовательной школой (до 200 м в юго-восточном направлении) и до границы жилой застройки (до 280 м в южном направлении)

    Nevoid basal cell carcinoma syndrome (NBCCS) is an autosomal dominant genetic disorder. It is commonly caused by mutations in PTCH1 and chiefly characterized by multiple basal cell carcinomas (BCCs) developing prior to the age of 30 years. In rare cases, NBCCS presents with a late onset of BCC development. To investigate BCC tumorigenesis in two brothers, who showed characteristic features of NBCCS but developed their first BCCs only after the age of 40 years. Two other siblings did not show signs of NBCCS. We obtained blood samples from four siblings and nine BCCs from the two brothers with NBCCS. Whole exome sequencing and RNA sequencing revealed loss of heterozygosity (LOH) of PTCH1 in eight out of nine tumours that consistently involved the same haplotype on chromosome 9. This haplotype contained a germinal splice site mutation in PTCH1 (NM_001083605:exon9:c.763-6C>A). Analysis of germline DNA confirmed segregation of this mutation with the disease. All BCCs harboured additional somatic loss-of-function (LoF) mutations in the remaining PTCH1 allele which are not typically seen in other cases of NBCCS. This suggests a hypomorphic nature of the germinal PTCH1 mutation in this family. Furthermore, all BCCs had a similar tumour mutational burden compared to BCCs of unrelated NBCCS patients while harbouring a higher number of damaging PTCH1 mutations. Our data suggest that a sequence of three genetic hits leads to the late development of BCCs in two brothers with NBCCS: a hypomorphic germline mutation, followed by somatic LOH and additional mutations that complete PTCH1 inactivation. These genetic events are in line with the late occurrence of the first BCC and with the higher number of damaging PTCH1 mutations compared to usual cases of NBCCS
